You can only add a new SPCOM line or SELEC question after you have created a new SPEC or have accessed an existing SPEC (see Creating a Specification to Entering Tabular Data).

You can only create a new SPEC as a member of a Specification World (SPWLD) element in a CATALOGUE DB. Check your current position in the hierarchy. (See Structure of the Catalogue Database and Content and Format of a Specification.) An accompanying message should give a fuller explanation.

You have specified two CATREF pointers in a heading line. The second entry will be ignored, but should preferably be deleted.

You can only create a new SPEC as a member of a Specification World (SPWLD) element in a CATALOGUE DB (see Structure of the Catalogue Database and Content and Format of a Specification).

The ditto symbol (+) means ‘repeat the corresponding entry in the preceding line’ and is therefore only valid in the second or subsequent lines of the table.

You must have created a new SPEC or accessed an existing SPEC before you can add to, modify, or output any tabulated Specification data (see Manipulating the Catalogue Database using SPECONMODE).

An element identifier in an SPCOM line must correspond to a relevant Reference Pointer in the heading line. It cannot be given as an answer under a SELEC question in the heading (see How Component Selection Works).

The identifier given in an OUTPUT command must refer to an accessible SPEC (see Outputting a Specification). Check that you have entered the identifier correctly.

You have specified two DETAIL pointers in a heading line. The line will be ignored.

If the answers in a given SPCOM line do not correspond in a relevant way with the SELEC questions in the heading then that SPCOM will be ignored. (See the Note in Selector Answers for one possible cause of this problem.)

The Specification /*LIMBOSPEC is reserved for holding REMOVED SPCOMs (see Deleting or Removing a SPEC or SPCOM). You cannot use it for any other purpose.

You can only use a DELETE or REMOVE command after you have accessed an appropriate SPEC (see Accessing an Existing Specification and Deleting or Removing a SPEC or SPCOM), otherwise SPECON does not know which Specification you are telling it to modify.

When adding a new SPCOM you must enter its TYPE (an AVEVA E3D™ noun) before its NAME. You may only use the reverse order when referring to an existing SPCOM (see Entering Tabular Data).

When using the COPY command, the SPEC into which the copy is transferred (name1 in Copying a Specification) must be empty. You cannot concatenate SPECs with the COPY command.

The REMOVE command can only be used to remove SPCOMs. You cannot remove an entire SPEC, although you may use the REMOVE ALL option to empty it of its contents (see Deleting or Removing a SPEC or SPCOM).

The text associated with a SPEC cannot exceed 50 characters in length (see Creating a Specification).

The SPEC named /*LIMBOSPEC, used to hold removed SPCOMs, is created automatically by AVEVA E3D™ and cannot be deleted, otherwise future REMOVE commands would not work (see Deleting or Removing a SPEC or SPCOM).

The REMOVE command applies only to the contents of a SPEC. Use REMOVE ALL to empty the SPEC of all contents or DELETE SPEC specname to eliminate the complete SPEC. (See Deleting or Removing a SPEC or SPCOM.)

The REMOVE command can only transfer SPCOMs to /*LIMBOSPEC. Only by re-entering an SPCOM under its existing name can it be transferred back from /*LIMBOSPEC into a user‑defined SPEC. (See Deleting or Removing a SPEC or SPCOM.)

You have specified two MATXT pointers in a heading line. The second entry will be ignored, but should preferably be deleted.

You have specified two CMPREF pointers in a heading line. The second entry will be ignored, but should preferably be deleted.

You have specified two BLTREF pointers in a heading line. The second entry will be ignored, but should preferably be deleted.

See Applicability for examples of valid GTYPEs.

You have specified two TMPR pointers in a heading line. The second entry will be ignored, but should preferably be deleted.
